Now time for my own opinion.
Pre Covid, I used to think that in general, the UK was one of the best countries to live in Europe. We have a fantastic public transport system (only downsides is the cost of tickets), schools and universities (only downside is that tuition fees in uni are very expensive, what a total disgrace) and loads of lovely places to visit (I love going around the South East by bus and train). We were also a safe country too. With Covid, I hate to say it, but this country has gone a bit down hill, with damage to the economy. So sad. We remain a safe country with lovely places to visit - but the economic damage that lockdowns have done is just sad.
Not everywhere is perfect, but after my degree in uni, I am considering doing 10-12 years of work experience, of which 5-6 in Australia (Sydney if possible, though I'll be happy with Brisbane, Perth or Adelaide) and the other 5-6 in Japan (Tokyo if possible, but I'll be happy with Osaka as a second choice). As some people have rightly pointed out on this forum, it's always a good idea to live abroad to see what's different when compared to the UK.
Now pros and cons about Italy since I'm half Italian and I own a second home there (not to mention I used to go to school in Italy from when I was 7 or 8 until I was 14). Italy has: fantastic weather, lovely places to visit, lovely beaches, great food, great healthcare. The food quality in Italian supermarkets is so great that it puts UK food quality to shame (with the exception of Lidl, M&S and Waitrose). And whilst in general public transport is crap - I'll give an exception to Naples Metro Line 1. In my opinion, this line has got to be the best ever metro line in Europe - lovely art and colourful stations (Toledo station was even voted as the best in Europe, not to mention one of the best in the whole world).
Now the downsides (which caused me to go back to the UK after I was 14): Italy suffers from corruption, bureaucracy, and a very crap public transport. It's alright if you are in the big cities, or if you are travelling from a big city to another (especially on Frecciarossa or Italo high speed). Want to catch a regional train, especially in the south? Be prepared for constant delays of up to 10 minutes or more (we Italians are perfectly used to it!), very short and overcrowded trains. I once had to sit on the floor for 2 hours from Cassino (a town on the Naples-Rome corridor) to Rome on a 3 car Pesa Atribo ATR 220 DMU, because the choice of 3 car was completely inadequate for an important service (the service originated from Campobasso - the largest city of the Molise region). Also, education isn't the best either - they don't teach English really well. And the majority of services are very inefficient as well.
So is anywhere else better? Well, depends where you go...
